java-vecmath1.2: Free version of vecmath from the Java3D 1.2 specification (source)

This is unofficial implementation(java source code) of the javax.vecmath package specified in the Java(TM)
3D API 1.2 . The package includes classes for 3-space vector/point, 4-space vector, 4x4, 3x3 matrix, quaternion,
axis-angle combination and etc. which are often utilized for computer graphics mathematics. Most of the
classes have single and double precision versions. Generic matrices' LU and SV decomposition are also there.

This is Free software, provided AS IS, with NO WARRANTY. Bug reports, comments are welcome.

Note that this implementation corresponds to Java3D 1.2 specification. My implementation has full
specification implemented and has full source code
